ASPERGILLUS EXPRESSION SYSTEM

Abstract: The present invention relates to a novel expression system in which A. japonicus-type species are used as host cells for expression of heterologous proteins.

Description: ASPERGILLUS EXPRESSION SYSTEM Field of the Invention The present invention relates to host cells useful in the production of recombinant proteins. In particular, the invention relates to fungal host cells of the genus Aspergillus, which can be used in the high-level expression of recombinant proteins, especially enzymes. Background of the Invention The use of recombinant host cells in the expression of heterologous proteins has in recent years greatly simplified the production of large quantities of commercially valuable proteins, which otherwise are obtainable only by purification from their native sources. Currently, there is a varied selection of expression systems from which to choose for the production of any given protein, including prokaryotic and eukaryotic hosts. The selection of an appropriate expression system will often depend not only on the ability of the host cell to produce adequate yields of the protein in an active state, but also to a large extent may be governed by the intended end use of the protein. Although mammalian and yeast cells have been the most commonly used eukaryotic hosts, filamentous fungi have now begun to be recognized as very useful as host cells for recombinant protein production. Among the fil ' amentous fungi which are currently used or proposed for use in such processes are Neurospora crassa, Acremonium chrysogenum, Tolypocladium geodes, Mucor circinelloides and Trichoderma reesei . In addition, certain species of the genus Aspergillus have been used effectively as host cells for recombinant protein production. Aspergillus is a deuteromycete fungus characterized by an aspergillum consisting of a conidiospore stipe terminating in a vesicle, which in turn bears one or two layers of synchronously formed specialized cells, variously referred to as sterigmata or phialides, and asexually formed spores referred to as conidia. The species Aspergillus nidulans has been reported to be transformed with recombinant plasmids (Ballance, et al. Biochem. Biophys. Res. Comm. 112: 284-289, 1983), but transformation was found to occur at fairly low frequency. Both Aspergillus niger and Aspergillus oryzae have also been described as being useful in recombinant production of proteins. However, other species of Aspergillus have not been shown to be useful in expression of heterologous protein, and in fact, because of poor expression and/or excessive production of proteases or mycotoxins, not all species of Aspergillus are suitable as host cells for this purpose, nor is this ability predictable from one species to the next. An ideal expression system is one which is substantially free of protease and mycotoxin production and large amounts of other endogenously made secreted proteins, and which is capable of higher levels of expression than known host cells. The present invention now provides new Aspergillus expression systems which fulfill these requirements. Summary of the Invention The present invention provides a host cell of an Aspergillus j aponicus-type species, such as the species Aspergillus japonicus, Aspergillus aculeatus or Aspergillus japonicus var. aculeatus, which host cell contains a nucleic acid sequence encoding a heterologous protein. By "heterologous protein" is meant one which is not native to the host cell, or a native protein in which modifications have been made to alter the native sequence. In a preferred embodiment the protein is a heterologous enzyme. The nucleic acid sequence is operably linked to a suitable promoter sequence, which is capable of directing transcription of the nucleic acid sequence in the chosen host cell. The invention also relates to a method for production of recombinant proteins, the method comprising culturing a host cell of one of the aforementioned species, which host cell contains a nucleic acid sequence encoding a heterologous protein, under conditions conducive to expression of the protein, and recovering the protein from the culture. In a preferred embodiment, the protein is a fungal protein, most preferably a fungal enzyme. The host cells and methods of the present invention are unexpectedly more efficient in the recombinant production of certain fungal enzymes than are other known Aspergillus species, such as A. oryzae. Detailed Description of the Invention The species A. japonicus, A. japonicus var. acu2eatus, and A. aculeatus all belong to the Nigri Section of the genus Aspergillus . The members of the section Nigri, as exemplified by Aspergillus niger, are characterized by radiate conidial heads and conidial masses in shades of black; globose vesicles; stipes which are smooth and hyaline, or pigmented below the vesicle; metulae present or absent, and often pigmented ("The Genus Aspergillus" , by K.B. Raper and D.I. Fennel, The Williams & Wikins Company, Baltimore, 1965) . Mutants of these strains differing in spore color and ornamentation, or other micromorphological characters also would be included in this section. Within the Nigri section of the genus Aspergillus, the delimitation of taxa is subject to debate, due to variation in colony color and conidiogenous structures on which the major classification schemes are primarily based (i.e., Raper and Fennel, supra) . The A. japonicus-r elated. taxa recognized by Raper and Fennel are A . japoni cus and A. aculeatus . Samson and Gams ("Advances In Penicillium and Aspergillus Systematics" , Samson and Pitt, eds., 1985) recognize A. japonicus only, and Al-Mussallam( "Revision of the Black Aspergillus Species", Ph.D. thesis, University of Utrecht, 1980) recognizes A. japonicus var. japonicus and A. japonicus var. aculeatus . The species A . japonicus is generally characterized by uniseriate sterigmata, and globose to subglobose, conspicuously echinulate conidia. The vesicles are commonly 20-35 μ, but range from 15-45 μ. The species was first described in Saito, Botan. Mag. 2Q_: 61-63, 1906. More specifically, the species is characterized as follows: Colonies on Czapek's solution agar growing rapidly at room temperature (24 * -26"C), in most strains 5.0 to 6.0 cm in diameter in 10 days, but in occasional strains less, consisting of a dense, white, irregularly wrinkled basal mycelium which tardily gives rise to a dense strand of conidial structures in purple-brown or purple-black shades, occasional strains producing abundant white to cream-colored globose sclerotia in central colony areas; reverse at first uncolored by later becoming purple drab and occasionally with a slight yellow-green tinge; exudate lacking; odor sometimes quite strong but not distinctive. Conidial heads variable, small, radiate or split into few indistinct columns, rarely exceeding 300μ in diameter at 10 days but in age sometimes distinctly columnar and up to 600-700 μ long or split into two divergent columns of similar length; conidiophores smooth or with a limited surface granulation, colorless or slightly pigmented particularly just below the vesicle, sinuous, mostly 500 to 1000 μ by 5 to 10 μ but varying greatly in these dimensions; vesicles somewhat colored in brownish yellow shades, often somewhat elongate but in older or larger heads more nearly globose, mostly 20 to 30 μ by 25 to 35 μ by ranging from less than 15 μ to 45μ in diameter, in normal heads fertile over most of their surface but in small heads at the apex only; sterigmata uniseriate, 5.5 to 8.0 μ by 3.0 to 4.5 μ, rarely swollen to double their normal size; conidia mostly globose, occasionally subglobose, strongly echinulate, with echines discrete and regularly space, commonly 0.5μ long, occasionally longer, spore bodies mostly 3.0 to 3.5 μ; sclerotia produced abundantly but tardily by some strains, white to cream, globose, up to 500 μ in diameter. Colonies on malt extract agar growing rapidly, 7 to 8 cm in diameter in 10 days at room temperature, more quickly and heavily sporulating than on Czapek's; conidial heads usually larger than on Czapek's and split into conspicuous columnar masses, commonly reaching diameters of 500 μ in 10 days and showing a narrower range of vesicle and stalk measurements; sterigmata and conidia as described above. The subspecies A. japonicus var. aculeatus is distinguished by the following characteristics: colonies on Czapek agar attaining 5.5 cm diameter in 14 days, consisting of fairly compact, irregularly wrinkled, white basal felt; some strains produce floccose aerial mycelium; reverse uncolored becoming brown with age; conidial heads produced in mass, purplish-brown near Quaker Drab and Dusky Drab, globose to radiate, splitting into well-defined divergent columns, 200- 300μ in diameter; conidiophore stalked smooth, hyaline or slightly pigmented at the apex, erect, from 350-4500μ, usually between 1000-2000 μ long, 9.0-13.5 μ wide; vesicles brown, 30-90 μ, usually 45-67 μ in diameter, bearing crowded philiades over the entire surface of large vesicles and over the upper three quarters in smaller ones; philiades 7.5-10 X 4-5 μ; conidia hyaline to brown, conspicuously echinulate, subglobose but mostly ellipsoidal, 4-5 X 3.5-4.5 μ; sclerotia produced abundantly in some strains, in concentric zones, globose to subglobose, 450-675 μ, but up to 800μ in diameter. The closely related species A. aculeatus is characterized generally by uniseriate sterigmata, and subglobose to definitely elliptical, conspicuously echinulate conidia. The vesicles are usually 60-80 μ, ranging from 35 to lOOμ. More specifically, the species is defined as follows: colonies on Czapek's solution agar growing rapidly at room temperature (24-26'C) , 5 to 6 cm in diameter in 12 days, plane, producing a dense stand of conidial structures, heavily sporing throughout in purple- brown or purple-black shades often with a slight gray-tan surface "bloom"; reverse uncolored or in fairly conspicuous yellow shades to near black at colony center, yellow pigment diffusible; exudate and odor lacking; white to cream colored sclerotia produced by occasional strains, most abundant at colony centers and at contiguous margins. Conidial heads globose at first, then splitting into relatively few compact divergent columns, reaching diameters up to 1 mm but commonly 500 to 700 μ, shattering easily with columns deciduous, individual heads often variable in color with conidia nearest the vesicles light tan; conidiophores uncolored or slightly brownish below the vesicles, usually 1-2 mm by 9 to 13 μ but up to 2.5 mm long and 18 to 29 μ in diameter with walls up to 2.0 to 2.5 μ thick, smooth or occasionally showing a limited deposit of granular material; vesicles often somewhat elongate when young, globose or nearly so when fully developed, heavy walled, commonly pigmented in brown shades and 60 to 80 μ in diameter but ranging from 35 to 100 μ, fertile over the entire surface; sterigmata in a single series, closely packed, 6.5 to 10.0 μ by 3.0 to 4.4 μ; conidia ranging from definitely elliptical to globose or nearly so, varying with the strain or within a single strain, mostly 3.5 to 4.0 μ by 4.5 to 5.0 μ, but with occasional cells measuring as much as 4 by 7 μ, in mounts showing a purplish tinge, conspicuously echinulate with echines discrete and rather widely spaced. This species was first described in Iizuka, J. Agr. Chem. Soc. Japan 27.: 806, 1953. It will be understood that throughout the specification and claims the use of the term "A. japonicus-type species" refers not only to organisms encompassed in the aforementioned three species, but also includes those species which have previously been or currently are designated as other species in alternate classification schemes, but which possess the same morphological and cultural characteristics defined above, and may be synonyms of A. japonicus, A. japonicus var. aculeatus or A . aculeatus . For example, synonyms of A. japonicus/A. japonicus var. japonicus include (but are not limited to) A. japonicus Saito var. capillatus Nakazawa, Takeda and Suematsu,-A. malvaceus Mosseray, A. atro-violaceus Mosseray, A . atrofuscus Mosseray, A . violaceo-fuscus Gasperini, A . brunneo-violaceus Bat. and Maia (Al-Mussallam, supra), and A. japonicus var. atrofuscus Iizuka (J. Agr. Chem. Soc. Japan 27: 807, 1953). Synonyms of A. aculeatus/A . japonicus var. aculeatus include (but are not limited to) A . yezoensis Sasaki (Al-Musallam, supra) , A. japonicus var. viridiflavus Iizuka (J. Agr. Chem. Soc. Japan 27: 807, 1953), and A . violaceo fuscus Gasperini (Atti. Soc. Toscana Sci. Nat. Pisa, 8(2): 326-328, 1887). Initial determination of candidate host cells is made by evaluation of the level of protease produced by the various isolates from over fifteen species in different taxonomic sections of the genus Aspergillus . This is accomplished by testing each isolate on a casein clearing plate assay at acidic, neutral and alkaline pH. Surprisingly, it is found that several members of the Section Nigri perform best in that they produced the smallest quantities of proteases, which could potentially cause degradation of any recombinant proteins produced. Based on this criterion, six species are chosen for further study, including A . japonicus, A. japonicus var. aculeatus, A. aculeatus, A. tamarii , A. carbonarius, and A. phoenicis . Attempts to transform the selected species are then conducted. Initial efforts focus on use of standard A. oryzae transformation techniques (Christensen et al., Bio/Technology 6: 1419-1422, 1988; EP Appln. No. 87 103 806.3). In brief, cotransformants are obtained using the A. oryzae protocol for protoplasting, transformation and selection for amdS or hygromycin B (hygB) marker genes. Expression vectors contain the A. oryzae TAKA-amylase gene, and the transcription termination signals from the A . niger glucoamylase gene, in addition to a heterologous coding sequence. Transformation frequencies vary from less than one to approximately 10 per microgram of DNA. In co- transformation experiments with the expression vectors detailed in the following examples, the frequency of co- transformation ranges from 0-60%. The transformed species are then observed to determine the level of expression of various heterologous enzymes. The heterologous enzymes tested include Humicola lanuginosa lipase (HLL) , Humicola insolens xylanase (Xylanase) , Humicola insolens cellulase (Cellulase) , Coprinus cinereus peroxidase (CiP) , and Candida antarctica lipase A. Surprisingly, the three species of the A. japonicus-like group showed the best expression for one or more of the enzymes, but in some cases, show better yield of enzyme than the control A . oryzae strains. In particular, a number of strains of each of A. aculeatus , A. japonicus, and A. japonicus var. aculeatus produce quite high levels of HLL (about one gram per liter) in shake flask culture. In addition, A. japonicus shows excellent production of xylanase in comparison with production of this enzyme in A. oryzae and A. niger strains. Moreover, A. aculeatus in a shake flask produces the Candida antarctica lipase A in the range of about 1.0 g/liter, which is about three to four times better than corresponding A. oryzae transformants grown under the same conditions. A summary of the results of these tests is provided in Table 2. As the results clearly show, several isolates of each species are capable of expressing heterologous protein. Thus, it is understood that this ability is not limited to a single isolate or strain, but rather is a characteristic of this group of species as a whole. Those skilled in the art will recognize that other strains or isolates of these species can also be used in expression of heterologous expression. Many strains of each species are publicly available in the collections of the American Type Culture Collection (ATCC) 12301 Parklawn Drive, Rockville Maryland 20852; Agricultural Research Service Culture Collection (NRRL) 1815 North University Street, Peoria, Illinois 61604; Fungal Genetics Stock Center (FGSC) , Kansas; Deutsche Sammlung von Mikroorganismen und Zellkulturen (DSM) , Mascheroder Weg IB, D-3300 Braunschweig, Germany; Institute of Applied Microbiology (IAM) , Tokyo University 1-1,1-Chome, Yayoi, Bunkyo-ku, Tokyo 113, Japan; Institute for Fermentation (IFO), 17-85 Juso-honmachi 2-chome, Yodogawa- ku, Osaka 532, Japan; and Centraal Bureau voor Schimmelcultures (CBS), Oosterstraat 1, 3740 AG Baarn, Netherlands, . The skilled artisan will also recognize that the successful transformation of the host species described herein is not limited to the use of the vectors, promoters, and selection markers specifically exemplified. Generally speaking, those techniques which are useful in transformation of A . oryzae, A. niger and A . nidulans are also useful with the host cells of the present invention. For example, although the amdS and hygB selection markers are preferred, other useful selection markers include the argB (A. nidulans or A. niger) , trpC (A. niger or A . nidulans) , or pyrG (A. niger or A. nidulans) markers. The promoter may be any DNA sequence that shows strong transcriptional activity in these species, and may be derived form genes encoding both extracellular and intracellular proteins, such as amylases, glucoamylases, proteases, lipases, cellulases and glycolytic enzymes. Such suitable promoters may be derived from genes for A. oryzae TAKA amylase, Rhizomucor miehei aspartic proteinase, A. niger glucoamylase, A. niger neutral α-amylase, A . niger acid stable α-amylase, and Rhizomucor miehei lipase. Examples of promoters from genes for glycolytic enzymes are TPI, ADH, and PGK. The promoter may also be a homologous promoter, i.e., the promoter for a native A . j aponicus-type gene. A preferred promoter according to the present invention is the A. oryzae TAKA amylase promoter. The TAKA amylase is a well-known α-amylase (Toda et al., Proc.Japan Acad. 5Jϋ Ser. B. : 208-212, 1982). The promoter sequence may also be provided with linkers for the purpose of introducing specific restriction sites facilitating ligation of the promoter sequence with the gene of choice or with a selected signal peptide or preregion. Terminators and polyadenylation sequences may also be derived from the same sources as the promoters. Enhancer sequences may also be inserted into the construct. To avoid the necessity of disrupting the cell to obtain the expressed product, and to minimize the amount of possible degradation of the expressed product within the cell, it is preferred that the product be secreted outside the cell. To this end, in a preferred embodiment, the gene of interest is linked to a preregion such as a signal or leader peptide which can direct the expressed product into the cell's secretory pathway. The preregion may be derived from genes for any secreted protein from any organism, or may be the native preregion. Among useful available sources for such a preregion are a glucoamylase or an amylase gene from an Aspergillus species, an amylase gene from a Bacillus species, a lipase or proteinase gene from Rhizomucor miehei , the gene for the α-factor from Saccharomyces cerevisiae, or the calf prochymosin gene. Most preferably the preregion is derived from the gene for A . oryzae TAKA amylase, A. niger neutral α-amylase, A. niger acid stable α-amylase, B. licheniformis α-amylase, the maltogenic amylase from Bacillus NCIB 11837, B. stearothermophilus α-amylase, or B . licheniformis subtilisin. An effective signal sequence is the A. oryzae TAKA amylase signal, the Rhizomucor miehei aspartic proteinase signal and the Rhizomucor miehei lipase signal. As an alternative, the preregion native to the gene being expressed may also be used. The gene for the desired product functionally linked to promoter and terminator sequences may be incorporated in a vector containing the selection marker or may be placed on a separate vector or plasmid capable of being integrated into the genome of the host strain. The vector system may be a single vector or plasmid or two or more vectors or plasmids which together contain the total DNA to be integrated into the genome. Vectors or plasmids may be linear or closed circular molecules. According to a preferred embodiment of the present invention, the host is transformed with two vectors, one including the selection marker and the other comprising the remaining heterologous DNA to be introduced, including promoter, the gene for the desired protein and transcription terminator and polyadenylation sequences. The present host cell species can be used to express any prokaryotic or eukaryotic heterologous protein of interest, and is preferably used to express eukaryotic proteins. The species A. japonicus and A. aculeatus are particularly useful in that each has been approved for use in the food industry. (Regulatory Aspects of Microbial Food Enzymes, Third Edition, The Association of Microbial Food Enzyme Producers, Brussels, Belgium) Of particular interest for these species is their use in expression of heterologous proteins, especially fungal enzymes. The novel expression systems can be used to express enzymes such as catalase, laccase, phenoloxidase, oxidase, oxidoreductases, cellulase, xylanase, peroxidase, lipase, hydrolase, esterase, cutinase, protease and other proteolytic enzymes, aminopeptidase, carboxypeptidase, phytase, lyase, pectinase and other pectinolytic enzymes, amylase, glucoamylase, α- galactosidase, β-galactosidase, α-glucosidase, β- glucosidase, mannosidase, isomerase, invertase, transferase, ribonuclease, chitinase, and deoxyribonuclease. It will be understood by those skilled in the art that the term "fungal enzymes" includes not only native fungal enzymes, but also those fungal enzymes which have been modified by amino acid substitutions, deletions, additions, or other modifications which may be made to enhance activity, thermostability, pH tolerance and the like. The present host cells may also be used in recombinant production of proteins which are native to the host cells. Examples of such use include, but are not limited to, placing an A. japonicus-type native protein under the control of a different promoter to enhance expression of the protein, to expedite export of a native protein of interest outside the cell by use of a signal sequence, or to increase copy number of a protein which is normally produced by the subject host cells. Thus, the present invention also encompasses such recombinant production of homologous proteins, to the extent that such expression involves the use of genetic elements not native to the host cell, or use of native elements which have been manipulated to function in a manner not normally seen in the host cell. The invention is further illustrated by the following non-limiting examples. I.Protease assays More than fifty strains, from at least fifteen different species, are examined to determine the amount of protease produced by each isolate, and also to observe their extracellular protein profile. To prepare culture inoculum, 10 ml of sterile distilled water is added to one 7-10 day old culture of each strain in a 9 cm petri dish, and spores are scraped gently from the mycelia to make a dense suspension. 2.5 ml of the suspension is used to inoculate 100 ml of ASP04 medium[ASP04 medium comprises lg/1 CaCl 2 , 2 g/1 yeast extract, 1 g/1 MgS0 4 , 5 g/1 KH 2 P0 / 2 g/1 citric acid, 0.5 ml Trace Metal solution (comprising 14.3 g/1 ZnS0 4 -7 H0, CuS0 4 -5H0, 0.5 g/1 NiCl 2 -6H 2 0, 13.8 g/1 FeS0 4 -7H 2 0, 8.5 g/1 MnS0 4 -H 2 0, and 3 g/1 citric acid), 1 g/1 urea, 2 g/1 (NH ) 2 S0 , 20 g/1 maltodextrin (8 ml of a 25% stock, added after autoclaving) in tap water, pH adjusted to 4.5 or 6.5 before autoclaving, then pH 4.5 adjusted with 8 ml 0.1M citric acid per 100 ml after autoclaving] . Flasks are incubated at 30 and/or 37'C, shaking on an orbital shaker at 200 rpm, for 5 days, in continuous light. Supernatant from the culture broth of each is spun at 2500 rpm for 5 minutes, and used in the casein clearing plate assay, which determines the levels of proteases produced by various fungal species being evaluated as potential candidates for recombinant protein expression. The casein plate clearing assay is conducted as follows. The plate medium is composed of 20 g/1 skim milk, 20 g/1 agarose, and 0.2M citrate-phosphate buffer for tests run at pH 5 and pH 7, and glycine NaOH buffer for tests run at pH 9. Milk powder is mixed with 100 ml of buffer and kept at 60'C. Agarose is mixed with 400 ml of buffer and autoclaved 5 minutes. After slight cooling, the warm milk mixture is added, and the mixture inverted gently 2-3 times to mix. The medium is poured into 150 mm plates using 50-70 ml per plate and stored at 5 * C until use. Just prior to use, twelve holes per plate are made in the agar. 25 μl of supernatant from fermentation of each strain is added to one plate of each pH and incubated overnight at 37'C. To pH 9 plates, 0.5M glacial acetic acid is added to precipitate casein and allow visualization of any clear zones. Each plate is then evaluated on clear zone size (i.e., from no zone to >2 cm in diameter) and zone type (i.e., clear, opaque or both types). The supernatants of each culture are also used to evaluate the strains' extracellular protein production. Novex (San Diego, California) 8-16% gradient gels, prepared according to manufacturer's instructions, are used to assess the protein profile. A 75 μl (3 and 5 day) sample of culture supernatant is mixed with 20μl of 5X dissociation buffer (dissociation buffer = 4 ml 1M Tris-HCl,pH 6.8, 1 g SDS, 617 mg dithiothreitol, and sterile distilled water to 10 ml), and glycerol/bromophenol blue (10-20 mg added to about 10 ml of 80-90% glycerol, and placed in boiling water for 1-2 hours to dissolve) , boiled for 5 minutes, cooled, loaded and run at 60-200 V until the bromphenol blue tracking dye reaches the bottom of the gel. The gels are silver stained according to the Biorad Silver Stain Plus Protocol (Biorad Laboratories, Hercules, CA) . Those isolates showing large numbers of bands are considered less suitable as potential new hosts, while those showing relatively clean profiles with only 1-4 major bands are considered for further testing. When the combined results of the protease assay and protein profile are reviewed, the majority of suitable potential candidates are found among the members of the section Nigri. Based on these results, the following isolates are selected for transformation studies: A. japonicus A1438 (CBS 568.65), A . aculeatus N1136 (CBS 101.43), A. aculeatus A1454 (CBS 172.66), A . aculeatus A1455 (CBS 186.67), A. japonicus var. aculeatus N0956 (IAM 13871), A. phoenicis A528 (CBS 139.48), A. phoenicis A530 (CBS 137.52), A. phoenicis E419 (CBS 137.52), A . carbonarius A3993 (IBT 4977), A . carbonarius ATCC 1025, A. tamarii E112 (ATCC 10836), A. tamarii N2266 (IFO 4358), and A . tamarii N2267(IFO 4142). These cultures are also maintained as part of the Novo Nordisk Biotech Culture Collection, Davis, California. II.Vector construction A. Selectable marker vectors. The vectors pJaL77 and pJaLl54 are used in transformation of host cells with the hygromycin B resistance selectable marker. This marker is based on the E. coli hygromycin B phosphotransferase gene, which is under the control of the TAKA promoter in pJaL 77 and the amdS promoter in pJaLl54. Briefly, these vectors are constructed as follows. The gene conferring resistance to hygromycin B is purchased from Boehringer Mannheim as plasmid pHph-1. This gene is equipped with an ATG codon as well as with suitable restriction sites at the amino and carboxy termini by PCR, using the primers: 5 ' -GCT CAG AAGCTT CCATCC TAC ACC TCA GCA ATG TCG CCT GAA CTC ACC GCG ACG TCT- 3" (N-terminal) and 3 ' -CGT CCG AGG GCA AAG GAA TAG CTCCAG AGATCT CAT GCT-5' (C-terminal). The PCR fragment is cut with the restriction enzymes BamHI and Xhol and cloned into the corresponding sites in the Aspergillus expression vector pToC68 (as described in WO 91/17243) to produce pJaL77. Plasmid pJaLl54 is constructed as follows. The amdS promoter mutant I 9 + I 666 (Hynes et al. Mol. Cell. Biol. 3(8): 1430-1439, 1983 and Katz et al. Mol Gen Genet. 220: 373-376, 1990) is cloned from plasmid pCaHj406 by PCR with the following primers (underlined regions represent homology to the amd-S promoter: CCT GGA TCC TCT GTG TTA GCT TAT AG and CTT GCA TGC CGC CAG GAC CGA GCA AG. The 694 bp PCR fragment containing the amd-S promoter is cut with BamHI and SphI and cloned into the corresponding site in pJaL77, so that the TAKA promoter in pJaL77 is exchanged with the amd-S promoter. The plasmid pToC90 containing the amdS marker is constructed by cloning a 2.7 kb Xbal fragment from p3SR2 (Hynes et al., supra) into an Xbal cut and dephosphorylated PUC19 plasmid. The derivative designated pToC186 is identical to pToC90 except that the promoter region contains two mutations (I 9 and I 66 6> known to enhance expression of the amdS gene (Hynes et al., supra; Corrick et al. , Gene 53: 63-71, 1987). B. Expression vectors. 1. Candida antarctica lipase. For expression of Candida antarctica lipase A, chromosomal DNA of the C. antarctica strain LF058 (DSM 3855) is extracted according to the methosd of Yelton et al. (PNAS USA 81: 1470-1474, 1984) The purified DNA is cut partially with Sau3A and after agarose gel electrophoresiε, fragments in the range of 3-9 kb are isolated. The sized Sau3A fragments are ligated into a BamHl-cut, dephosphorylated plasmid pBR322 (New England Biolabs) . The ligation mix is transformed into E. coli MT172. About 50,000 E. coli transformants are obtained, 80% of which contain an insert of LF058 DNA. By standard colony hybridization techniques, the colonies are screened with the 3 P-phosphorylated oligonucleotide probe NOR 440, a degenerate 17 mer based on the N-terminal sequence determined from mature C. antarctica lipase. 34 colonies appear positive after wash at low stringency(41 * C and 6 X SSC) . Plasmids were prepared from these colonies and analyzed by southern hybridization after restriction with BstNl. The probe for the southern is either the NOR 440 probe used for colony hybridization or a 32p-labelled probe NOR 438. NOR 438 is an oligonucleotide corresponding to amino acid sequence of the lipase in which, at 13 positions, a base has been chosen on the basis of codon use in yeasts and filamentous fungi. AACCCATACGACGACCC NOR 440 T C T T T G T GCTGCTC.T≤CCTAA£CCTTA£GACGACCCTTT£TAC.ACC.ACCCC NOR 438 T T T Guess positions are indicated. Only one plasmid, pMTl076, contains a band which hybridizes both to NOR 440 at low stringency and to NOR 438 at somewhat higher stringency (55"C and 1 X SSC) . PMT1076 is restriction mapped and the sequence determined by the Maxam-Gilbert method. The sequence is shown in Seq. ID NO. 1. The open reading frame is seen to encode a putative signal of 21 amino acids and also a propeptide of 10 amino acids preceding the N-terminal of the mature lipase. The last two amino acids of the propeptide are Arg, Arg, a typical cleavage site for endoproteolytic processing by enzymes of the S. cerevisiae KEX-2 type. The amino acid sequence is depicted in Seq. ID. No. 2. Through a number of standard plasmid manipulations (Maniatis et al.. Molecular Cloning. Cold Spring Harbor, NY, 1982), the open reading frame of C. antarctica lipase A is placed in the correct orientation between the alpha-amylase promoter of A oryzae and the glucoamylase transcription terminator of A . niger. The resulting expression plasmid is pMTl229. 2 . Humicola insolens xylanase. The vector pHD414 is a derivative of the plasmid p775(EP 238 023) . In contrast to this plasmid, pHD414 has a string of unique restriction sites between the TAKA promoter and the AMG terminator. The plasmid is constructed by removal of an approximately 200 bp long fragment (containing undesirable RE sites) at the 3' end of the terminator, and subsequent removal of an approximately 250 bp long fragment at the 5' end of the promoter, also containing undesirable sites. The 200 bp region is removed by cleavage with Narl (positioned in the pUC vector) and Xbal (just 3' to the terminator), subsequent filling in the generated ends with Klenow DNA polymerase + dNTP, purification of the vector fragment on a gel and religation of the vector fragment. This plasmid is called pHD413. pHD413 is cut with StuI (positioned in the 5' end of the promoter) and Pvull (in the pUC vector) , fractionated on gel and religated, resulting in pHD414. A strain of E. coli containing the approximately 1,100 bp xylanase Hindu/Xbal cDNA fragment in pYES is deposited in DSM as DSM 6995. The xylanase cDNA fragment is isolated from one of the clones by cleavage with Hindlll/Xbal. The fragment is purified by agarose gel electrophoresis, electroeluted, and made ready for ligation reactions. The cDNA fragment is ligated into pHD414 to produce pAXX40-l-l The sequence of the xylanase gene and protein are provided in SEQ ID NOS 3 and 4, and the gene is deposited as DSM (Deutsche Sammlung Von Mikrooroganismen und Zellkulturen GmbH) 6995. . 3 . Humicola insolens cellulase. Detailed characterization of the Humicola insolens cellulase is found in WO 91/17243. The expression vector pCaHj418 used for cellulase expression is constructed by excision of the 926 bp cellulase coding region fragment from pCaHj201 by cleavage with restriction enzymes BamHI and Sail. This fragment is purified by preparative gel electrophoresis using standard techniques and ligated with pHD414 (described above) which has been prepared by treatment with BamHI and Xhol. The resulting expression vector, pCaHj418, contains the cellulase gene under the transcriptional control of the A. oryzae taka-amylase promoter and the A. niger glucoamylase terminator region. 4. Humicola lanuσinosa lipase. Isolation and expression of the H. lanuginosa lipase gene is reported in EP 305 216, and in US Serial No. 07/236,605, the contents of which are incorporated herein by reference. Briefly, Total RNA is extracted from homogenized H. lanuginosa mycelium using methods as described by Boel et al. (EMBO J. 3: 1097-1102, 1984) and Chirgwin et al. (Biochemistry 18: 5294-5299, 1979) . Poly(A) -containing RNA is obtained by two cycles of affinity chromatography on oligo (dT) -cellulose as described by Aviv and Leder (PNAS USA 69: 1408-1412, 1972). cDNA is synthesized with the use of methods described by Okayama and Berg (Molec. Cell. Biol. 2: 161-170, 1982), and with the vectors pSP62-K2 and pCDVl-PL described by Noma et al. (Nature 319: 640-646, 1986). The synthesized cDNA is transformed into a hsdR- , M + derivative of E. coli MC1000 (Casadaban and Cohen, j.Mol. Biol. 138: 179-207, 1980) to generate recombinant clones. A mixture of 32 pentadecamer oligodeoxyribonucleotides A A A A A d( TT AA TG TT AA) , G G G G G one of which is complementary to H. lanuginosa lipase mRNA in the region coding for Phe-Asn-Gln-Phe-Asn is synthesized on an Applied Biosystems, Inc. DNA synthesizer and purified by PAGE. Approximately 10,000 E. coli recombinants from the H. lanuginosa cDNA library are transferred to Whatman 540 paper filters. The colonies are lysed and immobilized as described by Gergen et al. (Nucleic Acids Res. 7: 2115-2135, 1979). The filters are hybridized with the 32 P-labelled H. lanuginosa lipase-specific pentadecamer mixture as described by Boel et al. (EMBO J. 3: 1097-1102, 1984) . Hybridization and washing of the filters are done at 37'C and 43 "C, respectively, followed by autoradiography for 24 hours with an intensifier screen. Miniprep plasmid DNA is isolated from two hybridizing colonies, pHLL 702.3 and pHLL 702.4 by standard procedures (Birnboim and Doly, Nucleic Acids Res. 7: 1513-1523, 1979) and the DNA sequence of the DNA insert is established by the procedure of Maxam and Gilbert (Methods Enzymol. 65: 499-560, 1980) . To facilitate further construction work with the cDNA, DNA sequences containing unique restriction sites are added to the 5' and 3' ends of the cDNA as follows. pHLL 702.3 is digested with Sau961 which digests the cDNA in the 3' untranslated region and the resulting ends are filled in with E. coli DNA polymerase (Klenow fragment) and the four dNTPs. This DNA is subsequently digested with Sad which cuts the cDNA once just 3 ' to the initiating methionine codon. The resulting 0.9 kb cDNA fragment is purified by agarose gel electrophoresis; electroeluted and made ready for ligation reactions. As a 5 ' adaptor two oligonucleotides, 927 and 928, are synthesized. This adaptor is designed to add a HindiII and BamHI site just 5' to the initiating Met codon of the cDNA. The two oligos are kinased with ATP and T 4 polynucleotide kinase, annealed to each other and ligated to the purified 0.9 kb cDNA sequence in a pUCl9 vector digested with Hindi11 and Hindi and purified on a 0.7% agarose gel. The resulting plasmid carries the H. lanuginosa lipase cDNA as a portable 0.9 kb BamHI fragment. After BamHI digestion and purification of the 0.9 kb cDNA fragment on an agarose gel, it is ligated to BamHI and phosphatased p775 to generate p960 in which the lipase cDNA is under transcriptional control of the TAKA promoter from A . oryzae and the AMG terminator from A . niger. To prepare pMHan37, p960 is modified by replacing 60 basepairs of the 5 'untranslated region of the A . oryzae TAKA promoter just upstream to the Humicola lanuginosa lipase gene by the corresponding region from the A . nidulans tpiA gene (McKnight et al . Cell 46: 143-147, 1986) . A synthetic oligonucleotide containing the 5 ' untranslated region from the A . nidulans tpiA flanked at each end by 20 bases homologous to p960 sequences just outside the untranslated region is used in a PCR reaction together with another primer covering the BssHII-site in the TAKA promoter region. as the mutagenization primer covers the BamHI site close to the ATG start codon, the PCR fragment is digested with BamHI and BSSHII and recloned into p960 digested with BssHll and partially with BamHI. 200 bases upstream to the ATG in MHan37 is verified by DNA sequencing analysis. The sequence difference between p960 and pMHan37 is shown below: pMHan37 CATGCTTGGAGTTTCCAACTCAATTTACCTCTATCCACACTTCTCTT P960 CATGCTTGGAG...GATAGCAACCGACAACATCACATCAAGCTCTCC pMHan37 CCTTCCTCAACAATAAACCCCACAGGGG..GGATCC p960 CTTCTCTGAATCCTCTATATACACAACTGGGGATCC The sequence of the primer covering the BamHI site: 5 ' GCTCCTCATGGTGGATCCCCAGTTGTGTATATAGACCATTGAGGAAGGAAGA GAAGTGTGGATAGAGGTAAATTGAGTTGGAAACTCCAAGCATGGCATCCCTTGC 3 ' 5. Coprinus cinereus peroxidase. The isolation and cloning of the Coprinus cinereus peroxidase gene is described in WO 92/16634. Briefly, total RNA is extracted from homogenized Coprinus cinereus (IFO 8371) mycelium, collected at the time of maximum peroxidase activity as described by Boel et al. (EMBO J. 3_: 1097-1102, 1984) and Chirgwin et al. (Biochemistry 18: 5294-5299, 1979). Poly(A) -containing RNA is obtained by two cycles of affinity chromatography on oligo(dT) -cellulose as described by Aviv and Leder (PNAS USA 69: 1408-1412, 1972) . cDNA is synthesized by means of a cDNA synthesis kit from Invitrogen according to the manufacturer's instructions. About 50,000 E. coli recombinants from the Coprinus cinereus cDNA library are transferred to Whatman 540 paper filters. The colonies are lysed and immobilized as described by Gergen et al. (Nucleic Acids Res. 7: 2115-2135, 1979). The filters are hybridized with the 32 P-labelled 430 base pair peroxidase- specific probe in 0.2 X SSC, 0.1% SDS. Hybridization and washing of the filters is conducted at 65'C followed by autoradiography for 24 hours with an intensifier screen. After autoradiography, the filters are washed at increasing temperatures followed by autoradiography for 24 hours with an intensifier screen. In this way, more than 50 positive clones are identified. Miniprep plasmid DNA is isolated from hybridizing colonies by standard procedures (Birnboim and Doly, Nucleic Acids Res. 7: 1513-1523, 1979) and the DNA sequence of the cDNA insert is determined by the Sanger dideoxy procedure (Sanger et al., PNAS USA 74: 5463-5467, 1977) . The peroxidase cDNA fragment is excised from the vector by cleavage with Hindlll/Xhol and is purified by agarose gel electrophoresis, electroeluted and made ready for ligation reactions. The cDNA fragment is ligated to Hindlll/Xhol digested HD414 to generated pCip in which the cDNA is under transcriptional control of the TAKA promoter from A. oryzae and the AMG terminator from A . niger. pJVi9 is prepared from pCiP in that the restriction sites for Sad, Kpnl, Hindlll, PstI, Sail, and BamHI immediately preceding the peroxidase start codon are deleted. The cDNA sequence encoding the Coprinus cinereus peroxidase is shown in SEQ ID NO. 5 and 6. A summary of the expression vectors prepared is provided in Table 1. Table 1.

Transformation of Aspergillus hosts The following general procedures are used in transformation of all the strains tested, with exceptions noted expressly: 100 ml of MY50 medium is inoculated with spores of the strain to be transformed and incubated with shaking at 34° C for 1-2 days. The mycelium was harvested by filtration through miracloth and washed with 200 ml of 0.6 M MgS0. The mycelium is suspended in 15 ml of 1.2 M MgS0 4 , 10 mM NaH 2 P0 4/ pH = 5.8. The suspension is cooled on ice and 1ml of buffer containing 120 mg of Novozyme® 234 is added. After 5 minutes, 1 ml of 12 mg/ml BSA (Sigma type H25) is added and incubation with gentle agitation continued for 1.5-2.5 hours at 37° C until a large number of protoplasts is visible in a sample inspected under the microscope. The suspension is filtered through miracloth, the filtrate is transferred to a sterile tube and overlaid with 5 ml of 0.6 M sorbitol, 100 mM Tris-HCl, pH = 7.0. Centrifugation is performed for 15 minutes at 2500 rpm and the protoplasts are collected from the top of the MgS0 4 cushion. Two volumes of STC (1.2 M sorbitol, lOmM Tris-HCl pH = 7.5, 10 mM CaCl 2 ) are added to the protoplast suspension and the mixture is centrifuged for five minutes at 1000 X g. The protoplast pellet is resuspended in 3 ml of STC and repelleted. This is repeated, and then the protoplasts are resuspended in 0.2-1 ml of STC. 100 μl of protoplast suspension is mixed with 5-25 μg of the appropriate DNA in 10 μl of STC. Each strain is cotransformed with an expression vector containing the structural gene of interest (see Table 1) , and a plasmid containing a selectable marker. Plasmids pToC90 and pToCl86 contain the A . nidulans amdS gene, and are used for transformation and selection for growth on acetamide as the sole nitrogen source. Plasmids pJaL77 and pJaLl54 are used for transformation and selection of resistance to hygromycin B. The mixtures are left at room temperature for 25 minutes. 0.2 ml of 60% PEG 4000 (BDH 29576), 10 mM CaCl 2 and 10 mM Tris-HCl pH = 7.5 is added and carefully mixed twice and finally 0.85 ml of the same solution is added and carefully mixed. The mixture is left at room temperature for 25 minutes, spun at 2500 X g for 15 minutes and the pellet resuspended in 2 ml of 1.2 M sorbitol. After one more sedimentation the protoplasts are spread on the appropriate plates. Protoplasts are spread on minimal plates (Cove, Biochem. Biophys. Acta 113 : 51-56, 1966) containing 1.0 M sucrose, pH = 7.0, 10 mM acetamide as nitrogen source (when amdS is the selection marker) and 20 mM CsCl to inhibit background growth. The medium differs when hygB is the selection marker in the use of 10 mM sodium nitrate as nitrogen source, and the presence of 150 μg/ml hygromycin B. As an alternate to the final centrifugation step, resuspending and spreading, 8 ml of STC can be added and mixed with the protoplasts, and 3 ml are added to each of 3 selection plates, which are then swirled to cover the plate. After incubation for 4-7 days at 37'C colonies with conidia are picked, suspended in sterile water and spread for isolation of single colonies. This procedure is repeated and spores of a single colony after the second reisolation are stored as a defined transformant. IV. Evaluation of recombinant protein expression Following the above procedure, individual isolates of the selected strains are co-transformed with one of the expression vectors noted in Table 1, and one of the plasmids containing a selectable marker mentioned in the preceding example. Each of the co-tranformants is then tested in the appropriate assay to determine expression of the gene of interest. A. Lipase Cotransformants for lipase activity are cultured in a M400Da medium consisting of 50 g/1 maltodextrin, 2g/l MgS0 4 -7H 2 0, 2g/l KH 2 P0 4 , 3g/l K 2 S0 , 4g/l citric acid, 8g/l yeast extract, 3g/l (NH ) 2 S0 4j 0.5 ml Trace metal solution, 4 ml 50% urea solution (autoclaved separately) , in 1 liter of distilled water, pH 6.0, and 5g/l yeast extract made up in tap water to 800 ml. pH is adjusted to 4.5 before autoclaving. After autoclaving, 166 ml filter sterilized 1M urea (to give a final concentration of lOg/1) and 35.3 ml of filter sterilized 1M NaN0 3 (to give a final concentration of 0.3%) are added. Lipase activity in culture filtrates is measured using p-nitrophenylbutyrate (pNB) as a substrate. A stock solution of pNB is prepared by adding 104.6 μl of pNB to 5 ml of DMSO. To each well of a microtiter plate is added 90 μl of 50mM Tris, pH 7. Ten μl of sample is added to each well, and mixed by shaking the microtiter plate for about one minute. Just prior to the assay, 20 μl of pNB stock is combined with 970 μl of 50 mM Tris buffer, pH 7 and mixed. Immediately prior to assaying for lipase activity using a commercial plate reader, 100 μl of the pNB-Tris mixture are added to each sample well and absorbance measured at 405 nm over a 3 minute time period. The assay is temperature sensitive, so an internal standard is used with each sample set. The slope determined for each sample directly correlates to lipase activity; the linear range of the assay is from about 0.005 to 5 μg lipase per milliliter. In this type of assay, the specific activity of H. lanuginosa lipase is determined to be approximately 4000 LU/mg, whereas the specific activity of Candida lipase A is about 400 LU/mg. B. Xylanase All xylanase transformants are grown in medium with the following composition, in g/1: maltodextrin, 50; MgSo 4 -7H 2 0, 2.0; KH 2 P0 , 10.0; K 2 S0 4 , 2.0; citric acid 2.0; yeast extract, 10.0; AMG trace metal solution, 0.5ml; urea, 2.0;pH 6.0. All the transformants are grown as submerged, agitiated cultures at 34'C. Xylanase activity in culture broths is determined using 0.2% AZCL-xylan (Megazyme Co. Australia) suspended in a citrate phosphate buffer, pH 6.5. The culture fluid is diluted, usually 100-fold, and 10 μl of diluted culture fluid is mixed with 1 ml of 0.2% AZCL-xylan substrate. The mixture is incubated at 42'C for 30 minutes. The reaction mixture is mixed well every 5 minutes. At the end of incubation, the undigested substrate is precipitated by centrifugation at 10,000 rpm for 5 minutes. The blue dye released from this substrate is quantified by absorbance at 595 nm and the amount of enzyme activity in the culture broths is calculated from a standard made with an enzyme preparation with known activity. An endoxylanase unit (EXU) is determined relative to an enzyme standard prepared under identical conditions. C. Cellulase Cellulase transformants are grown in MY50 medium (50 g/1 maltodextrin, 2g/l MgS0 -7H 2 0, lOg/l KH 2 P0 4 , 2g/l K 2 S0 4 , 2g/l citric acid, 10 g/1 yeast extract, 0.5 ml trace metals, 2.0 g urea, at 34 * C as submerged cultures. Cellulase activity is measured using 0.2% AZCL-HE- cellulose (Megazyme) as a substrate suspended in 0.1M citrate-phosphate buffer at pH 6.5. The culture is diluted in 0.1M citrate buffer, pH 6.5, and 10 μl of diluted culture fluid is mixed with 1 ml of 0.2% AZCL-HE-cellulose. The mixture is incubated at 42 * C for 30 minutes with shaking every 5 minutes. After incubation, the undigested substrate is pelleted by centrifugation at 10,000 rpm for 5 minutes. The blue color in the supernatant is quantified spectrophotometrically at 595 nm, and the amount of enzyme activity is determined from a standard curve made with a known cellulase standard. Endocellulase units (ECU) are determined relative to an enzyme standard prepared under identical conditions. D.Peroxidase Cotransformants for CiP are cultured in a M400Da medium consisting of 50 g/1 maltodextrin, 2g/l MgS0 -7H 2 0, 2g/l KH 2 P0 4 , 3g/l K 2 S0 , 4g/l citric acid, 8g/l yeast extract, 3g/l (NH 4 ) 2 S0 4/ 0.5 ml Trace metal solution, 4 ml 50% urea solution (autoclaved separately) , in 1 liter of distilled water, pH 6.0. Peroxidase expression is monitored using ABTS as a substrate or by rocket immunoelectrophoresis compared to a standard of known concentration. For immunodiffusion, 1% agarose in TM buffer (1.3g/l Tris base, 0.6 g/1 maleic acid, pH 7) is melted and cooled to 55'C. 400 μl of rabbit antiserum against CiP is mixed with 15 ml of agarose, spread and solidified on a 10cm x 10 cm plate. CDM agar(lg/l K 2 P0 4 , 30 g/1 sucrose, 0.3g/l NaN0 3 , 0.05g/l KCl, 0.05g.l MgS0 -7H 2 0, O.OOlg/1 FeS0 -7H 2 0, O.OOlg/l ZnS0 4 -7H 2 0, 0.0005g/l CuS0 -5H 2 0, 20g/l maltrodextrin, 15g/l agarose) culture samples of CiP transformants grown for 7 days at 37°C in CDM are applied to 5 mm holes made in the agar plate. The protein is allowed to diffuse for 48 hours. The plate is stained with coomassie blue R to visualize the protein-antibody precipitation zone. As a standard solution, purified is used at the concentrations of 500, 1000, and 2000 peroxidase units (PODU)/ml; 1 PODU is the amount of enzyme which under the standard conditions catalyzes the conversion of 1 μmol hydrogen peroxide per minute. To determine peroxidase by the ABTS (2,2'-azinobis(3- ethylbenzothiazoline-6-sulfonate) method, 2 ml of 2mM ABTSfO.110 g ABTS, Boehringer Mannheim No. 102946 in 0.1 M phosphate buffer (10.63 g disodium hydrogen phosphate dihydrate p.a. M6580, 5.49 potassium dihydrogenphosphate p.a. M4873 in de ineralized water up to 1 liter) is preheated for 10 minutes at 30'C. To this is added 10.6 mM H 2 0 2 solution(1.0 g Perhydrol Suprapur® 30% H 2 0 2 Merck 7298 in demineralized water up to 25 ml), and 0.2 ml of sample or standard (standard = 5.0 mg Kem-En-Tec, grade 1, No. 4140A in phosphate buffer up to 25 ml, diluted 400 times) in a glass tube. The reaction is conducted at 30°C for three minutes. The absorbance of the sample is measured at 418 nm against milli Q demineralized water and followed for three minutes. The best reflection of peroxidase activity is given by the absorbance difference: ΔA = A( 75 Sec )~ A (i 5 sec ). The absorbance difference should lie between 0.15-0.30 corresponding to 0.05-0.1 PODU/ml in the sample. VI. Results and Discussion Table 2 summarizes the expression levels of various heterologous fungal enzymes produced by the alternative host of the present invention. It can be seen from the table that all strains were successful in expression of at least one of the genes of interest. In several cases, the new host strains give unexpectedly high levels of enzyme. For example, at least one strain of each of A . aculeatus, A . japonicus, and A. japonicus var. aculeatus yields surprisingly high levels of HLL in shake flask cultures (approximately one gram per liter) , demonstrating that these species are capable of expressing large quantities ofheterologous protein. In fact, the levels of production of HLL produced by these transformants appear to be as good as or better than the best primary transformants of A. oryzae. A. japonicus also is shown to be an excellent host for the production of xylanase compared with A. oryzae and A. niger BoδO. The shake flask yields for this enzyme are approximately twice the levels seen for the best A. oryzae transformants. A. aculeatus strain A1455 also shows good production of Candida antarctica lipase A, giving shake flask yields in the gram per liter range, which is about three to four times better than corresponding A . oryzae primary transformants grown under the same conditions.
